Question

A nurse is assessing the heart sound of a client who reports substernal precordial pain. Identify which of the following sounds the nurse should document in the client's medical record by listening to the audio clip.

a. S1 - Lub.
b. S2 - Dub.
c. S3 - Gallop.
d. S4 - Murmur.

Answer 1

The nurse should document S1 - Lub heart sound in the client's medical record. S1 is the sound created by the closing of the atrioventricular valves during ventricular contraction, and it is commonly described as a 'lub' sound. It is heard when the mitral and tricuspid valves close after the atria contract and blood is pushed into the ventricles.

Step-by-step explanation:

The nurse should document S1 - Lub heart sound in the client's medical record. In a normal, healthy heart, S1 is the sound created by the closing of the atrioventricular valves during ventricular contraction. It is commonly described as a 'lub' sound. This sound is heard when the mitral and tricuspid valves close after the atria contract and blood is pushed into the ventricles.
